If the other party also agrees to divorce, the court may ask both of you to mediate (in China's civil cases, mediation is a necessary procedure, you will not be organized to mediate before the court session, and you will also be asked if you are willing to mediate). If the mediation is successful, a Civil Mediation Statement will be issued.
